[Bug 1608880] Re: systemd doesnt work with timed fsck, only with counted mount fsck

[Nils Kassube]

I can confirm this bug. However /forcefsck seems not to be supported
because it isn't mentioned in the man page.

When I log in to one of the 16.04 systems, I get this info:

*** /dev/sda5 will be checked for errors at next reboot ***

But the command "dmesg|grep -i e2fsck" gives this output:
[   14.999711] EXT4-fs (sda5): warning: checktime reached, running e2fsck is recommended

So the interpretation of the check interval seems to be a recommended
value only during boot.

Title:
  systemd doesnt work with timed fsck, only with counted mount fsck

Status in systemd package in Ubuntu:
  Confirmed

Bug description:
  Updated my homserver from 14.04 to 16.04. Got a "/dev/sda1 will be
  fscked on next reboot" hint in the MOTD. Did some reboots and the fsck
  never happend. Tried with "sudo touch /forcefsck" but the message
  didnt go away. Thought it was an error of the MOTD scripts and tried
  to fiddle with them. But it reappeard ever time.

  Looked at the syslogs logs and saw the fsck never happend.

  Looked at the output from dumpe2fs and it showed several interesting informations:
   * the mount count was 12 and the maximum mountcount of 34 was not reached
   * the timed fsck date was reached
   * the last fsck was long ago (next confirmation the /forcefsck didnt work at all)

  i changed the mount count to 35 with "sudo tune2fs -C 35 /dev/sda1"
  which made the fsck on next reboot.

  So what works: 
   * mount count fsck on reboot

  what doesnt work:
   * setting /forcefsck manually
   * timed fsck 

  what should work?
   * all 3 of them should work.
